Embodiment Construction

[0012] figure 1 Module 1 is a GPS receiver module, IC1 is an integrated circuit for RS-232 and TTL signal level conversion, IC2 is a single-chip integrated circuit, and Module 2 is a single-bus sensor module.

[0013] figure 2 , image 3 , Figure 4 , Figure 5 It is the program flowchart solidified in the single-chip integrated circuit IC2 in the embodiment of the present invention.

[0014] The working principle of this circuit is: GPS receiving module Module 1 receives the positioning signal and inputs it to the signal level conversion integrated circuit IC1, converts the RS-232 level to TTL level and then inputs it to the serial port receiving end of the single-chip integrated circuit IC2; The bus sensor module Module 2 sends the signal directly to the IC2 receiving port; the program in IC2 automatically runs and completes the GPS positioning signal and the signal sent by Module 2 to receive and composite; the composite signal is output from the IC2 serial port output to th...

Abstract

The present invention relates to a program control GPS signal and digital signal composite circuit. It is characterized by that after the location signal of GPS receiving module is passed through RS-232 and TTL signal level conversion integrated circuit and is converted, it can be inputted into the single-chip computer integrated circuit, the digital signal of single bus sensor module is directly inputted into the single-chip computer integrated circuit, the firmware program in the single-chip computer integrated circuit can be used for processing the inputted GPS signal and digital signal and outputting composite signal, then it is passed through RS-232 and TTL signal level conversion integrated circuit and converted again, and is outputted.

Description

Technical field [0001] The invention relates to a program-controlled GPS signal and digital signal composite circuit, in particular to a program-controlled GPS signal and digital signal composite circuit used to equip various atmospheric sounding instruments and GPS positioning instruments. Background technique [0002] At present, there are two ways to combine GPS signals and digital signals in well-known sounding instruments that use GPS positioning. One is to use response command to control switch circuit conversion for compounding; the other is to use signal string detection tail adding method for compounding. Both of these two signal composite methods have the disadvantages of complex circuits, prone to error and high cost, which affect the popularization and application of radiosonde instruments using GPS positioning. Summary of the invention [0003] The technical problem to be solved by the present invention i...
